How to convert MKV to MP3?
You can convert MKV to MP3 with MConverter in three easy steps:
Choose MKV files from your device or cloud storage
At the top of this page, drag and drop your MKVs.
Alternatively, click on the Browse box to select files with your device's file picker, or copy and paste an MKV file by pressing Ctrl+V (or ⌘+V on Mac).
MConverter can easily import MKVs from Google Drive, OneDrive, and Dropbox.
Converting a folder with MKV files to MP3 is also supported: simply paste, drag and drop it, or use the ADD FOLDER button.
Click or tap on MP3 from the list of target formats
You could also use the search box at the top right to quickly find the format you need, whether it's MP3 or something else.
Get your MP3 files after MConverter has finished processing them
Click on DOWNLOAD ALL to save your MP3's to your default downloads folder, or select SAVE TO to choose another location.
You can also configure automatic file downloads during the conversion process or in the settings menu. When enabled, each MP3 file is downloaded as soon as its conversion is complete, without waiting for the others to finish.
If supported by your device, you'll see a Share icon, allowing you to directly send converted files to other apps.

Mime type

Format description
MKV files are MatrosKa Video files. Like the Russian Matryoshka doll, which contains multiple smaller dolls nested inside each other, the MKV format can contain multiple video, audio, and subtitle tracks inside a single file. This makes it convenient to have one video with a number of audio and subtitle tracks in different languages, all inside a single playable file.

Mime type

Format description
MP3 is a commonly used audio format. The audio data is compressed inside the file, which is why MP3 files take up less space than WAV, for example. Even though the audio is compressed, the quality is still good enough for most personal use cases.
Common questions about converting MKV to MP3
Can I convert MKV to MP3 in bulk?
Yes, MConverter supports batch converting of multiple MKVs to MP3's simultaneously. You can even drag and drop folders containing MKVs to convert to MP3. Pasting MKV files and folders copied in the clipboard also works: use Ctrl+V.
Can I convert an MKV file to MP3, if its size is 2 GB?
Yes, with MConverter Pro you can convert big MKVs, up to 2 gigabytes each. The free version lets you convert files up to 100 MB. If you need to convert MKV files over 100 megabytes, try MConverter Pro. If your files aren’t over 1 GB, then you can use MConverter Plus instead, as it’s cheaper.
